WINDOW FRAME AND SASHES.

Application led April 1, 191B.

To all whom t may concern.'

Be it known that I. Hallar E. CAMPBELL, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a certain new and useful Improvement in Window Frames andSashes, of which the following is a specilication.

The invention is a window-frame and sash, wherein all the structuralparts are of wood, except. the laterally extending metal sash plates andmetal angle-bare therefor. The invention consists in the cmistructionmore particularly hereinafter described.

ln the aceou'ipanying drawingS Figure 1 is an elevation showing' aportion of the two sashes and of the jamb adjacent thereto, the jambiall being broken away at its upper portion to show the underlying partsin vertical section. Fig. 2 is a Section on the line 2, 2 of Fig'. 1.

Similar letters of reference indicate like parts.

A and B are .sliding sashes, provided with any suitable counterbalancingmeans, not shown. The sash frames are of wood, and the glass panes C areseated in said trames and secured by stripe D in any suitable way. Thetwo j ambs respectively on opposite sides ol the Sashes are alike, sothat a description of one jamb applies to both. Said jambes are hollow,and their walls are of wood. One of said jambe is shown at E, andcoinprises the following parts: a rear wall F, an outer eide wall G, afront wall H, and an inner side Wall forme/d as hereinafter described.The outer side wall (l is secured to the rear Wall F and to the frontwall H. Seated at one edge in a mortise in rear Wall F is a wooden bar Iwhich projects into the space within the jamb and is parallel to wall G.Secured to the face of bar I is a artition J with the faoe of which thesaches A, B are in sliding Contact, said bar covering the joint betweensaid sashee. The outer member K oi the inner jamb wall is secured tofront jamb wall H, and the inner member L is secured to rear wall F andpreferably meets bar I.

Between the lnember K and partition J and between partition J and memberL are gaps or vertical slots, which extend from top to bottom of thejamb. In the gap between member K and partition J are two angle-stripsM, N of metal, the apexes of the angles facing one another--a spacebeing Specification of Letters Patent.

left between said apexea. These angle-Strips are respectively secured lotheir supports--- namely, member K and partition .l --in any suitableway. ,Preferably as shown. I insert one arm of the strip in a mortisr inits` snpport and attach the other arm to a4 suitably beveled portion ot'said support. In the gap between partition J and member L are twoSimilar Strips 0, P, respectively secured to said partition J and memberil in the inanner already described. e

0n the sashes A, B are laterallyextending metal platee Q. Il. 'whichprrtrrably enter niortises in the edges ot' aaiil :;as l1e1. and may besecured therein by mi rs S. The plate Q. on sash ll euri-.rs iirtwi--fothe anglestrips M. N'. and the planli on sash A enters between theangle-ships: (l. l). VBoth plates, therefore` enter the janib andpreferably terminate at their irre Vertical edges in slidinlr contactwith the bar I. I preferably secure upon the face of bar I, means forprotecting said tace against the w ar thereon due to the sliding` oisaid plates, such as a metal plate T. against which the free edges ofSaid plates hear.

It will be obvious. from the foregoing that ill the structural :membersarr ot wood, excepting the lateral plates Q, Il, the anglo strips M. Nand (l7 ,E and` when present, the wearingY plate T: also, that marketwooden sasbes can here be uned, since the lateral metal plates Q, It areeasily attached to them. Metal angleetrips are also obtainable, and canbe applied by any house earpeuter.

I claim:

1. A window-frame and sash construe" tion, comprising a hollow jamb ofwood. having in itsl inner wall a vertical slot, metal angle-stripssecured on opposite sides of said slot, with the aporrea of their anglesapproximated, a sa ih of Wood., and on said sash. a laterally intending'metal plate enterini:r said jamb through. said slot between and ineontmt with .said angrleetrips.

2. A window-frame and sash, as in claim 1, the said laterally extendingplates being received in mortises in the Side rails of said sash.

il, each of said angle-strips having one arm entering; and secured inthe. jamb wall adjacent to said slot, and the other arm bearing upon asupport.
